Bisping, previously set to face Demian Maia at the event, was last seen picking apart Jason Miller at the Ultimate Fighter 14 Finale to pick up his fourth consecutive win including victories over Yoshihiro Akiyama and Dan Miller. The 32-year old Brit holds an overall record of 22-3 with eighteen stoppages to his credit, a stark difference from his newly named adversary who owes more than half of his total wins to the judges’ scorecards.

The outspoken Sonnen (26-11-1) is also coming off an impressive win, submitting Brian Stann this past October, and has also found success inside the Octagon against a number of respectable opponents such as Yushin Okami and Nate Marquardt.

UFC on FOX 2 features a main event between light heavyweights Rashad Evans and Phil Davis with a crack at 205-pound title-holder Jon Jones on the line. Maia will now take on undefeated blue-chipper Chris Weidman in place of Bisping.

MMATraining Take: My heart goes out to Munoz as I have no doubt today’s injury was crushing to him on a personal level given the stakes involved. That being said, while I respect Bisping’s confidence, having less than two weeks to prepare for Sonnen is a major gamble to take given Chael’s wrestling. Granted, Maia is a grappler too but he’s a BJJ guy rather than someone who makes his living taking people down and holding them there.
